This Group Containers folder stores shared data used by Avast Security components on Mac, letting the app and its helpers access common settings and resources.
What is 6H4HRTU5E3.group.com.avast.osx?
6H4HRTU5E3.group.com.avast.osx is a shared app-data folder in ~/Library/Group Containers used by Avast Security on macOS. Group Containers let a Mac app and its related background components read and write common data in one place instead of keeping everything inside a single app bundle. For a security app, this shared area can hold settings, support files, status information, and other data needed by the main interface and helper processes to work together. Users typically encounter this folder when reviewing storage, removing security software, or cleaning up files left behind after uninstalling an app. If Avast Security is still installed, removing this folder can break app features, reset configuration, or cause background components to stop working correctly.

Safety overview
Status: Mostly safe
This folder is associated with Avast Security for Mac and storing shared data in a Group Containers location is consistent with how macOS apps and helper components exchange settings and support files. The main caution is functional rather than malicious: deleting it while Avast Security or related background helpers are still installed can remove shared configuration and disrupt scanning, notifications, or other security features. If you do not intentionally use Avast on this Mac, check for installed Avast apps and login/background items before deleting the folder so you do not leave a partial uninstall behind.
Recommendation: Keep this folder if you actively use Avast Security on your Mac. If you have already uninstalled Avast or no longer want it, remove Avast using its normal uninstaller first, then delete this leftover Group Containers folder if it remains. That approach reduces the chance of broken background items or repeated prompts from orphaned components.
